Hi 2B,...

Sounds like either of your choices would be good!! However I wouldn't want you to overlook another possibility,... the Goldberg Tiger 60!! There are quite a few posts and threads here that rave about the Tiger 60's flying characteristics, which should put a smile on your face just reading them.

The Tiger 60 is regarded by quite a few as a "poor-mans" pattern plane!! It flys that smooth!! Set up right I've seen them compete in pattern competiton. In fact I flew the smaller .40 size Tiger 2 to a district championship my first year in pattern competition!! They are that good!!

Check out the Tiger 60,... its an easy build and you get a great flying plane as a result!! Don't get me wrong, I'm not knocking your other choices, as I have no doubt they are a great flying plane as well, but you shouldn't overlook the Tiger 60!!

As far as engine choices,... I love four strokes so I would opt for the 91 Surpass. However if that engine is already in another airplane and you've got the finances for a third engine, check out the Saito 91. I believe for the displacement the Saito has more power and they are rock solid reliable engines!! Once again,... I'm not knocking, as the OS 91 Surpass is an excellent engine. Just given the option I'd choose the Saito.

Sincerely,
Steve T.
